Convert M4B Files

M4B is a proprietary Apple-designed multimedia format used for storing audiobook files using the MPEG-4 container format.

The M4B format is not very popular among users, therefore they will often convert their M4B files to more common multimedia formats.

One may ypically encode a M4B track to an MP3 file, because there is a wide range of apps and devices that support it.

One will also be able to select any other target audio format supported by the M4B converter they have selected.
